What that was used for -- yeons ago -- was to make a mum (and a few other flowers I can't remember right now) on w/royal icing. Not much to use it for now that I can think of........oh, dry gp &/or fondant; make lattice ball cages??

I have only used the flat nails, too. I tried to find instructions/directions for any flower using that nail, but Google and Wilton didn't show anything. I'd love to see how people use it. I think I have one in a box somewhere.
